In 1972, a Swedish model posed nude for ‘Playboy’. Years later, we have the JPEG format thanks to this

The one of Lena Sjööblom It is one of the most delirious races in the history of technology. To begin with, because when she made her mark in the sector she was not an engineer, nor a mathematician, nor a physicist, nor anything that resembled her in the slightest. Nor did it have any known “Eureka” moment nor did it contribute any discovery or invention. No. Sjööblom was a model. From a model she became what was then known as a “Playboy girl.” And from the pages of the nude magazine he jumped to the front-line research that today, half a century later, allows us to enjoy the JPEG image format. Let’s go in parts. In the early 70s, Sjööblom, a 21-year-old Swedish immigrant Recently landed in the US, she made a living as a model. To make her way and probably without the slightest idea of ​​the journey her image would end up taking, at the end of 1972 she agreed to pose nude for Playboya magazine that at that time sold millions of copies around the world. In one of the central photos that he took of him Dwight Hookerone of the most famous portrait painters of the city, appears from behind, in front of a mirror, with no clothes other than a hat, a red boa, stockings and heels. I liked his work. A lot. At least that’s what we can deduce if we take into account that the November 1972 issue, in which Sjööblom was the playmate main feature and Pamela Rawlings was on the cover, sold 7.16 million copiesmaking it the most successful in the magazine’s entire history. The pose became so famous that in 1973 Woody Allen He even snuck it into one of his movies. As often happens with fame, that sudden public interest came, swept away and, with it, evaporated. Sjööblom continued her modeling career and, once retired, returned to Sweden. Chances of life, one of those 7.16 million copies of the 1972 magazine ended up in the hands of a person linked to the Signal Image Processing Institute (SIPI) of the University of South Carolinaa laboratory in which, at that time, they worked on image processing and were laying the foundations of what would end up being the JPEG and MPEG standards. The coincidence would not be of greater interest if it were not for the fact that that reader took his Playboy to SIPI at the right time: just when They were looking for an image for their tests. The right place, at the right time Today it may seem crazy for someone to show up at the office with a nude magazine under their arm. Not in the 70s. As Lorena Fernández remembersof the University of Deustoin The Conversationnot only was it common for the staff to show themselves with their Playboy in teams that, like Carolina’s, were made up solely of men. It was even well seen, just like doing it today with The Times or the guide with the programming of La 2 documentaries. In that context, the arrival of Sjööblom’s photos was as well received as it was proverbial. Around June or July 1973, electrical engineering professor Alexander Swachuk, one of his graduate students, and the manager of SIPI were madly looking for a photo that they could scan and include in one of their presentations on image compression. They had their own stock, of course, but it was made up of files inherited from the boring and trite television standards of the early ’60s. The Swachuk Team I wanted a human face and an image that was also bright to guarantee a good output dynamic range. And what better option —they thought— that Sjööblom’s face? Skipping all the rules on property rights and decorum, the researchers used the image of Playboy. They kept only the top third of the magazine’s central poster and placed it under their muirhead scannerequipped with analog-digital converters and a minicomputer Hewlett Packard 2100. Jamie Hutchinson details To stay with a section of 512×512 pixels, they scanned 5.12 inches of the top of the photo, which in practice showed only Lena Sjööblom’s face, her shoulders and part of her bare back. The result showed a software error that forced the team to retouch it, but Swachuk’s team was working against the clock and decided to keep the distorted and altered image. The fact is that he liked it. Just as I had liked Sjööblom’s photo shoot in Playboy at the end of ’72. “They asked us for copies and we gave them to them so they could compare their image algorithms with ours on the same test image,” the professor himself recalled some time later. The final process At the SIPI they turned Sjööblom’s portrait into a test image for digital compression and transmission work. Arpanetthe precursor of the Internet. And that, with the passage of time, had an unpredictable result: the image of that model that everyone began to refer to as “Lena” or “Lenna” and whose origin began to blur became the standard used by other researchers who wanted to compress similar files with their algorithms. The face of that twenty-year-old Swedish woman, with a hat and a bare back, was replicated in books, conferences, articles, traveled through the “Atapuerca” of the Internet and helped lay the foundations for the JPEG image format. “Many researchers know the Lena image so well that they can easily evaluate any algorithm that runs on it. That’s why most people in the industry seem to believe that Lena has served well as a standard,” comments Hutchinson. In addition to being a “familiar image”, the photo combines shadows, highlights and blurred and sharp areas and details, a mixture that makes it “a tough test for an algorithm processing”. Perhaps the most curious thing about the entire story is that so much Playboy Like Lena Sjööblom herself, they spent decades without knowing the exorbitant fame—and the important role—of the 70s portrait.

Some Swedish scientists decided to drug salmon with cocaine and then release them. It happened just what was expected

There is more than just fish and algae in the world’s rivers. More or less diluted amounts of chemicalsincluding pesticides, pharmaceuticals and illegal drugs. He checked it a few years ago a team from King’s College that, after taking samples in various parts of the county of Suffolk, in England, found cocaine and ketamine residues. Researchers have long known that wildlife is exposed to these compounds, but one question remained: How do drugs affect them in their natural environment? To find out in Sweden have drugged to dozens of salmon. Drugging salmon? That’s how it is. It sounds strange, but it is exactly what a group of scientists from Griffith University, the Zoological Society of London and the Max Planck Institute, among other organizations, have done. They basically took 105 salmon (salmo salar) from a fish farm, they divided them into several groups and added implants that supplied them with drugs. Then they released them. More or less as in the famous case of Cocaine Bearbut in a planned way. How did they do it? 35 of those salmon were implanted with a special device that slowly released coca into their bodies. A similar system was incorporated into others, although modified to provide benzoylecgoninethe main metabolite of cocaine. The third group did not receive any substance to act as a control. Once prepared, the salmon, all young specimens, were released into Lake Vätternsouth of Sweden. For eight weeks the researchers dedicated themselves to finding out how each group behaved. The specimens in the experiment wore a special tracking device, so (with the help of sensors installed around the lake) scientists could follow their trail and calculate how far they swam. And what did they find out? That the drugged salmon behaved very differently from the ‘sober’ ones. Especially those who received benzoylecgonine. After releasing the fish on the southwest bank of the Vättern, the researchers found that the salmon exposed to coca swam on average five more kilometers than the ‘clean’ ones, a considerable difference that falls short, however, when the specimens to which the metabolite was supplied are analyzed. They swam almost 14 km more, which led them to enter the northern area of ​​the lake. “The team found that fish exposed to benzoylecgonine swam up to 1.9 times farther per week than those not exposed and dispersed up to 12.3 km farther,” duck Griffith University. The agency also clarifies that the changes “became more evident” as the days passed, which shows that exposure to coca alters the behavior of fauna. Why is it important? Let the drugged salmon swim more kilometers and cover more space than others without ‘doping’ is more important than it may seem. These behavioral changes influence aspects such as what places the fish occupy, where they feed or the risks they face. More kilometers also translates into greater physical effort, which forces the salmon to look for more sources of nutrition to recover energy. “Where fish go determines what they eat, what eats them, and how populations are structured,” comment Dr. Marcus Michelangeli. “If pollution is driving these patterns, it has the potential to affect ecosystems in ways we are only beginning to understand.” But that was already known, right? Yes. And no. We knew that aquatic fauna is exposed to the drugs that we consume. The 2019 study in Suffolk and others, such as the made in 2016 in Puget (Washington), during which researchers detected traces of Prozac, Lipitor and cocaine in the body of salomes. We also knew that these substances alter the behavior of wildlife. In fact, scientists they already checked how water fleas exposed to coca swim faster or crabs are more reckless. The really interesting thing about the study carried out in Sweden is that it has allowed us to go one step further: to leave the laboratories, which were the isolated space in which these types of experiments had been carried out until now, and carry out research in natural environments and the same conditions that fauna is found. It hasn’t been easy. Although the team guarantees that the entire experiment has been done in safe conditions for the ecosystem and humans. Obtain all necessary permits, they confess researchers, it was “a tedious process.” And what to do now? Dr. Jack Brand, from the Swedish University of Agricultural Sciences, recognize that more studies are needed to fully understand the consequences of pollution in rivers, lakes and seas. It is an important issue, among other reasons because the substance that has most altered salmon is benzoylecgonine, which has a special impact. “It was the metabolite, which we know is found in higher concentrations in nature, that had a much more profound effect on the behavior and movement of the fish,” warns in statements to Guardian. “This suggests that if we perform evaluations without including compounds such as these metabolites and their derivatives, we could be overlooking an important part of the environmental risks to which we expose these animals.” Images | Colin Davis (Unsplash), Katmai National Park and Preserve (Flickr) and Scazon (Flickr) In Xataka | In 2001, a yacht took refuge on a remote island in the Atlantic.

There is a neighborhood in Spain with so many Swedish tourists that it is already a “Little Sweden”. And it’s exactly where you imagine.

Neighborhoods change, they transform. That has always happened. What is less common is that the change is accompanied by new accents, especially Scandinavian accents, which is what has been gaining strength in decades. Saint CatherinePalma de Mallorca. What was once a fishing neighborhood has mutated into something totally different: an area in which there are many businesses oriented to the hospitality and the real estate market and in which it is surprisingly easy to find expats arriving from cities like Stockholm. There are those who already refer to the neighborhood as “little Sweden”. ‘Little Sweden’. The transformation of Santa Catalina is not exactly new. In 2017 Mallorca Diary realized and how the Scandinavians had acquired so many stores and apartments that the neighborhood had earned the nickname “Little Sweden.” It was not a phenomenon exclusive to that specific coastal area (at expats They are attracted to Mallorca in general), but it is true that it was clearly visible in its streets. What is surprising is to see how the scandinavization of Santa Catalina has advanced in the last decade, something that makes it quite clear a chronicle published by elDiario.es. “There are few Mallorcans left”. Probably the best way to understand the change is to listen to its residents, like Antoni, a 79-year-old neighbor who, after a lifetime in Santa Catalina recognize that he hardly knows anyone anymore when he walks through its streets. “There are few Mallorcans left,” he resigns. His environment agrees with him. The man talk with the press in an area where it is not difficult to find recently renovated buildings and shop windows silk-screened in foreign languages, including English, German and Swedish. If you look a little, not far from there you can even find real estate agencies focused on the Scandinavian market and the sign of an old Swedish bakery. A neighborhood in full change. Antoni is not (far from it) the only local who notices the changes in the neighborhood. Tomeu confirm that “there are only some old businesses left” and Raúl, also raised in Santa Catalina, confirms that none of the friends he played with when he was a child no longer live there. That neighborhoods change over the decades (and that extends to both neighborhoods and businesses) is nothing extraordinary, nor exclusive to Santa Catalina, Palma or the Balearic Islands. What is curious is that this change has as one of its driving forces the landing of expats and capital of northern Europe. More than testimonials. The transformation of the neighborhood (Mallorca in general) can be followed through more than just testimonies and memories. The studies do not always allow us to go into detail about each district, but they confirm the profound changes that the archipelago has experienced in recent years. To begin with, the Balearic Islands are the region of Spain with highest percentage of foreign population. According to a report of the Funcas Foundation, 29.3% of its population was born outside of Spain. As a reference, in Madrid they represent 25.7%. In 2004, foreigners represented ‘barely’ 15.3% of the Balearic census. Expensive, but not ‘Stockholm level’. The Swedes they are very far away of being a majority group in the Balearic Islands, but for some time they have shown a special interest for the region. Almost a decade ago the local press explained that many discovered its islands as a vacation destination and, over time, chose to settle in the archipelago, attracted by its climate, quality of life and prices. “There are the small things, like having a coffee for example. In Stockholm it costs five or six euros,” recognized in 2017 Patric, at the head of a practice located precisely in Santa Catalina. “In Stockholm the square meter is around 10,000 euros and that is why Santa Catalina is still cheap. For the rest of the world the neighborhood is terrible, but for the Swedes it is quite cheap.” Agency pending. Another front that makes the transformation of the neighborhood clear is real estate. for your article elDiario has spoken with several agencies established in the area and more or less focused on the Scandinavian market, such as Mallorcabyrån Real Estatewhich presents itself as a “Swedish-speaking real estate agency in Mallorca”, or Svensk Fastighetsförmedlingwhose managers they boast of having “brought the reliable Swedish real estate model to Spain”. Escalating prices. Beyond the agencies, the Idealista portal also offers an interesting clue. The real estate portal specifies that right now the m2 in Santa Catalina-Son Armadans-Maritim is paid at 6,200 eurosfar from the 2,385 a decade ago. In fact, Idealista has registered a year-on-year increase of 14.3%. Things don’t get much better if we talk about the residential rental market. The m2 is paid at 19.7 euros5.6% more than a year ago. Rental options right now more economical In the area there is a 50 square meter apartment for which they ask for 1,100 euros per month and a 38 m2 studio for which they pay 1,150 euros. In this last case (a room without an elevator), yes, the advertisement clarifies that it is a “seasonal rental.” Why do prices increase? The transformation of the neighborhood is clear and can be followed both through testimony of its oldest neighbors as well as of the newspaper archive, which takes years strengthening the “little Sweden” label. However, not everyone is so clear that the rise in housing prices can be explained by the arrival of Scandinavian capital. “In general, the main factor behind the lack of housing at affordable prices in Palma is the shortage of supply, especially new construction,” claims Vivian Grunblatt, head of a real estate agency aimed, among others, at Swedish buyers. “In the last ten years the creation of new homes has been limited, which generates constant pressure on prices.” “And what are you doing?” There are also who raises it from another perspective, like Raúl, the horse who recognizes that there are no longer any of his childhood friends left in the neighborhood.

Europe needs tungsten for its electrical future. A Swedish mining company knows where to find it: Ourense

In the parish of Pentes, in the Ourense municipality of A Gudiña, the excavators have already begun to remove earth. There, on a slope where until recently only the mountain wind could be heard, the Swedish mining company Eurobattery Minerals AB has launched the work to extract tungsten – also known as tungsten –, a strategic metal for the European energy and technological transition. Galicia thus joins the small group of regions on the continent with active exploitation of this critical mineral. A strategic mine for Europe. The company, through its Galician subsidiary Tungsten San Juan, has launched its San Juan project while preparing its application for the second call for Strategic Projects under the European Regulation of Critical Raw Materials (CRMA), to open in January 2026. The first earthworks and the construction of a service warehouse are already visible in the area, as confirmed by the Vigo Lighthouse. When it is at full capacity, this will be the second active exploitation of tungsten in Spain, along with that of Barruecopardoin Salamanca. More in depth. The San Juan project will be an open pit mine with a goal that goes beyond local production: to provide European tungsten to the continent’s new industrial ecosystem. The company has begun improving infrastructure and constructing a pilot plant with gravimetric technology, while estimating reserves of 60,000 tons of ore with a grade of 1.3% WO₃. These are modest figures on a global scale, but significant for a Europe that seeks to reduce its dependence on Chinese imports of this critical metal. It has not been a short road. The procedures began in 2016 with geological studies, surveys and the construction of accesses, all under the supervision of the Xunta de Galicia. “Our goal is to produce tungsten responsibly and efficiently within Europe,” explains Agne Ahleniusgeneral director of Tungsten San Juan and former head of the Barruecopardo mine. “With this project, Galicia and Spain reinforce their role in the European supply chain of critical raw materials.” The metal that supports the energy transition. Few materials concentrate as much strategic value as tungsten. Its density, its resistance and its very high melting point make it a key resource for modern industry: from wind turbines to defense, including semiconductors and electric cars. But behind its technical brilliance there is a global conflict. China controls more than 80% of production and, in recent months, it has further limited its exports. The result: skyrocketing prices, uncertainty in the markets and a new reminder of how dependent Europe continues to be. To break this cycle, Brussels has launched the Critical Raw Materials Act (CRMA), a plan to guarantee access to critical minerals within European territory. According to the European Commissionthese initiatives not only seek economic stability: they also aim to reinforce the industrial autonomy of the continent and reduce its vulnerability to geopolitical tensions. Spain, a mining window. The start of the San Juan project is not an isolated event. It is part of a larger movement: the rediscovery of Spain’s mining potential. The country has projects of copper, tungsten, vanadium, graphite and cobalt, in addition to new deposits of rare earths in Estremadura and Gran Canaria. The European Union has set clear goals. It wants to stop depending on third countries for its supply of raw materials, and the new Critical Raw Materials Regulation (CRMA) mark the way: By 2030, at least 10% of critical minerals must be extracted within Europe, 40% processed on EU soil and 15% from recycling. Furthermore, no external country may concentrate more than 65% of the supply. On this map, Spain appears as a key piece: with Galicia, Castilla y León, Andalusia and Extremadura at the forefront, the country could become one of the gateways to the new European green reindustrialization. European autonomy is in Galicia. The roar of the excavators in A Gudiña not only marks the beginning of a new mine, but also the symbol of a change of era. Europe wants to leave decades of dependence behind and build a more sovereign and sustainable industry. From a Galician hillside, a small tungsten mine has become part of that strategy. What begins in Pentes may be, deep down, one more piece of the new energy and technological map of Europe. Image | Unsplash Xataka | The price of silver is exploding to levels not seen since 1980. The reason: we need too much

There are those who use chatgpt to create a vacation plan. Swedish prime minister uses it to govern

Ulf Kristersson, Prime Minister of Sweden and leader of the country’s conservative coalition, He has publicly recognized that consults artificial intelligence tools such as Chatgpt and Mishwner (Mistral European chatbot) to obtain “second opinions” in its government decisions. A statement that has unleashed a political and academic storm about the risks of using AI in such critical sectors as public and citizen management. In the focus. In An interview With the Dagens Industri Economic newspaper, Kristersson not only admitted their personal use of these tools, but also revealed that their collaborators also employ them in their daily work. “I use it quite often, even if it is to obtain a second opinion” said the prime minister. Apparently, Kristersson claims to use the tools to ask things like “What have others done? Or should we think just the opposite?”, He explained about the questions he asked. A devastating reaction. The Actonbladet newspaper accused directly to Kristersson having “fallen into the psychosis of the AI of the oligarchs.” Meanwhile, some experts have shown concern about security and democratic implications. Simone Fischer-Hübner, researcher and computer expert at the University of Karlstad, warned about the dangers of introducing sensitive information in Chatgpt: “You have to be very careful.” The warning makes sense, since although the company has security and privacy measures, any conversation we have with the chatbot ends on OpenAi servers. Therefore, it is not a very safe approach, especially if we talk about such a critical use as in the political dome. Beyond security. Virginia Dignum, professor of artificial intelligence responsible at the University of Umeå, assures that AI cannot offer significant opinions about political ideas, since it simply reflects the biases of those who developed it. “The more it depends on AI for simple things, the greater the risk of excess confidence in the system. It is a slippery slope,” he warned. And he finished with a phrase that has turned the world around in networks and media: “We do not vote for Chatgpt.” A defense that does not convince. Kristerson spokesman Tom Samuelsson tried to minimize controversy ensuring that the prime minister does not handle sensitive information through these platforms and that he uses them “more as a general reference.” However, Jakob Ohlsson, an expert in AI, Point out that even seemingly harmless information can reveal patterns of government strategic thinking to technology companies in charge of this type of systems. It is these types of examples that show us The great adoption that have had these types of systems, regardless of the sector in which they work.
